In most shops I’ve been in, people already know where the problems are and what the solutions are. Yes, vendor products (like BMC, Compuware, Quest) are useful in finding problems and solutions.
But the real problem is that when confronted with the opportunity to fix a problem. management chooses to not fix. The culture rewards those who pretend that problems don’t exist. It does not reward those who seem to have a negative attitude. Pretending problems don’t exist is often part of the path to promotion.

A prophet in his own country is another facet of the culture. Your own people can accurately tell you the problem and soltuion. But management won’t believe it until a high priced outsider says it. And the higher the price of the outsider, the more management is likely to believe it, regardless of the skill level of that outsider.
